Secondary ion mass spectrometry for geochemical microanalysis

拟议的研究计划集中在二次离子质谱（SIMS）在天然材料微分析中的持续发展和应用。提出的关键应用包括研究者当前感兴趣的几个子领域：1)矿床地球化学；2)海洋生物矿化中的古海洋学代用物；3)俯冲相关火山作用的稳定同位素系统学。为这些程序开发的SIMS技术在地球科学的一般领域内也有多种附加应用。研究方法将强调SIMS的独特能力，用于非常精细的空间分辨率和精确的痕量元素和稳定同位素微量分析固体。为支持该计划而开发的玻璃和矿物参考材料也将有利于并促进纪念大学SIMS设施和地球科学界其他微量分析设施的更多大学使用。

The proposed research program is centred on the ongoing development and application of Secondary Ion Mass Spectrometry (SIMS) to the microanalysis of natural materials. The key applications proposed encompass a number of subfields of current interest to the investigator i) Ore Deposits Geochemistry, ii) Paleoceanographic Proxies in Marine Biomineralization, and iii) Stable Isotope Systematics of Subduction-Related Volcanism. The SIMS techniques developed for these programs also have manifold additional applications within the general field of Geosciences. The research approach will emphasize the unique capabilities of SIMS for very fine spatial resolution and precise trace element and stable isotopic microanalysis of solids. The glass and mineral reference materials developed in support of this program will also benefit and promote additional collegial use of the Memorial University SIMS Facility, and other microanalytical facilities in the geosciences community.
